WATER-HEATER.

Specification of Letters Patent.

Patented Sept. 5, 1911.

Application filed October 8, 1909. Serial No. 521,659.

To all whom it may concern Be it known that I, IDA F. C. CURTIS,acitizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented a new and usefulVVater-Heater, of which the following is a specification.

This invention relates to water heaters of that type better known asinstantaneous heaters.

One of the objects of the invention is to provide a compact device ofthis character including one or more tanks constituting storage meansand whereby a plentiful supply of hot water can be readily obtainedimmediately after the burner has been lighted.

Another object is to provide an attractive device of this class whichcan be readily set up close to a bath tub or the like and having meanswhereby hot water can be supplied directly from either the coil or thetank which is supplied from the coil.

With these and other objects in view, the invention consists in certainnovel details of construction and the combinations of parts hereinaftermore fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a central vertical section through aheater embodying the present improvement. Fig. 2 is a horizontal sectionthrough the top portion of the hood or casing and showing the balance ofthe mechanism in plan, said section being on the line AB, Fig. 1. Fig. 3is a vertical section through a portion of the apparatus and showing theoutlet pipe of the water coil in side elevation. Fig. A is a sectionthrough a portion of the burner. Fig. 5 is a longitudinal sectionthrough a portion of one of the rings of the burner, the top portionthereof being removed.

Referring to the figures by characters of reference, 1 designates a baseor pedestal having upstanding arms 2 supporting a drip pan 3. A drainpipe 4: extends downward from the center of the drip pan and is designedto direct accumulated moisture into a pan 5 which is mounted on thepedestal 1 as shown in Fig. 1. Angular legs 6 extend downward from aburner 7 of novel construction, said burner being made up of concentricrings 8, each of which is preferably substantially semicircular in crosssection, all of the rings being connected by means of webs 9 castintegral therewith. The said rings 8 communicate with a supply pipe 9which can be of any preferred construction and is designed to beattached to a service pipe whereby gas maybe readily directed into therings 8. Each of these rings has a cap 10 also formed of a ringsemi-circular in cross section, said rings being connected by means ofintegral webs 11. The widths of the cap rings 10 are slightly greaterthan those of the base rings 8 so as to enable said cap rings to lap theperipheral edges of the rings 8. The outer edge of the outer base ring 8and the inner face of the outer portion of the outer cap ring 10 arescrew threaded and designed to interengage when the rings 10 are turnedin one direction, this resulting in the securing of all of the rings 10upon the rings 8. Apertures 12 are formed in the peripheral edges of theinner base rings 8 and also in the inner edge of the outer ring 8, theseapertures or notches being only partly covered by the cap rings andtherefore constituting outlets for the gaseous fuel. It will be apparentof course that when the cap rings are secured upon the base rings theyform tubes or gas chambers. Cross straps 13 are arranged upon the burnerformed of the cap rings 10 and base rings 8 and these straps haveupstanding brackets 14 at the ends thereof and which support the watercoil 15 of the heater. The coil has its outer convolution merging intothe discharge pipe 16. The pipe for directing water to the coil has beenindicated at 17 Arms or brackets 18 extend laterally and upwardly fromthe arms 2 and mounted on these last mentioned arms 18 is a frame 19supporting one or more closed tanks or receptacles 20. In the presentinstance, two of these tanks have been shown, the same being spacedapart and arranged above but at opposite sides of the burner and watercoil. The outlet pipe 16 of the water coil extends upward and opens intoa pipe 21, the end of which opens into the bottom portions of the tanks20, there being a valve 22 within the pipe 16, whereby the flow of waterinto the pipes 21 and tank 20 may be cut off if desired. Another pipe 23extends from the pipe 16 at a point below the valve 22 and terminates ina faucet 24 arranged at any suitable point, there being a valve 25 inthe pipe 16 below pipe 23 for cutting off the supply of water to thefaucet from the coil. One or more branch pipes 26 may be extended fromthe pipe 23. An overflow pipe '27 extends from the upper portions of oneof the tanks 20 and may be provided with a faucet 28 at the terminusthereof, there being a valve 29 for controlling the flow of water to thefaucet. One or more branch pipes 30 may be extended from this overflowpipe as shown, to conduct the overflow to any suitable point should thefaucet 28 be closed. An outlet flue 31 is. extended upward from the topof a hood or casing 32 which incloses the tanks 20 and extends downwardto the burner 7, this flue being provided with a damper 33 whereby theescape of the products of combustion can be readily controlled.

In using the device herein described the gaseous fuel is directed intothe burner through the feed pipe 9 and the gas will ignite where itescapes through the openings 12 in the base rings 8. The flames willcome in direct contact with the convolutions of the water coil and thewater contained within this coil will be quickly heated. If the valve 22is opened, the heated water will flow into the tanks 20 where it will bestored for future use, the said stored water being maintained at a hightemperature by the products of combustion passing through the hood orcasing 32 to the flue 31. When it is desired to use the water, the valve22 can be closed and the valve 25 opened whereupon the water is free topass directly from the water coil to the point of use or, if preferred,the valve 22 can also be opened whereupon an increased supply of waterwill flow, not

only from the coil but also from the tanks.

By closing the valve 25 and opening valve 22, the coil may be shut offfrom the faucet 24 and all the water in tanks 20 will thus be suppliedto said faucet. The pipe 27 constitutes a means for permitting anynecessary overflow and will also allow steam to escape should thepressure within the tanks become too great. It is of course to beunderstood that a suitable safety valve should belocated at some point,preferably within the pipe 30.

A hood 34 may be located directly over the coil 15 to deflect the heatpassing therethe burner.

As heretofore pointed out it will be apparent that by closing the valve25 and opening valve 22 hot water, which has been stored in the tanks20, can be drawn oil through the faucet 24:, said water flowing throughpipes 21 and 23 to said faucet. The coil is, of course, at this time outof com munication with the faucet. By opening valve 25 and closing thevalve 22, water can be caused to flow directly from the coil to thefaucet 24 and communication between the tanks 20 and said faucet will beclosed.

What is claimed is 1. In a water heater, the combination with a burner,of a tank thereabove, a water coil supported above the burner, a feedpipe extending to the coil from a source of supply and from said coil tothe tank, a valve within said pipe connections between the coil and thetank for controlling the passage of water from the coil to the tank, apipe extending from said connection between the coil and the valve forconveying water to the point of use from the source of supply and thecoil when the valve is closed and from the tank when the valve isopened.

2. A water heater including a burner, spaced closed tanks supportedthereabove and forming a fine therebetween said flue being located overthe burner, a housing extending over and around the tank and having atop outlet, a water coil interposed between the burner and the saidflue, means for directing water to the coil from a source of supply, apipe connection between the coil and the tanks, an outlet pipe extendingfrom said connection for directing water from either the tanks or thecoil to the point of use, and valves for controlling the passage ofwater to said outlet pipes from the coil and tank respectively.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
